McGillivray,
First, welcome to the Forum
You will find a lot of help here.
My Factory Wiring Diagram for model year 1977 consists of nine multi-lief pages:
0.1-3/47 – 4-lief; “
Current flow diagram, Type 911S, USA, Model 77”; Tracks 1 – 62; XXXV, 1977.
0.1-3/49 – 4-lief; “
Current flow diagram, Type 911S, USA, Model 77”; Tracks 63 – 128; XXXV, 1977.
0.1-3/39 – 2-lief; “
Additional current flow diagram air conditioner with front condenser”; Tracks 1 – 9; XXXV, 1976.
0.1-3/43 – 1-lief; “
Additional current flow diagram engine compartment light”; Tracks 1 – 3; XXXV, 1976.
0.1-3/45 – 2-lief; “
Additional current flow diagram, remotely controlled outside mirrors, Type 911”; Tracks 1 – 9; XXXV, 1976.
0.1-3/51 – 1-lief; “
Additional current flow diagram, brake booster, Type 911”; Tracks 1 – 8; XXXV, 1976.
0.1-3/53 – 1-lief; “
Additional current flow diagram, speed limiter, Type 911”; Tracks 1 – 5; XXXV, 1976.
0.1-3/61 – 2-lief; “
Additional current flow diagram power windows Type 911 from model 77”; Tracks 1 – 10; XXXVI, 1977.
0.1-3/63 – 2-lief; “
Additional current flow diagram Air Conditioner (M399) Type 911 from model 77”; Tracks 1 – 10; XXXVI, 1977.
I would be interested to know if any of these were superseded (later Supersession Roman number) or if there are any additional diagrams for the ’77 model year.
Perhaps we can get the latest version scanned and added to the Pelican
Tech Center Pelican Parts - Porsche 911 Parts Listings & Diagrams.
Best,
